Engineers have created a bacteria-filtering membrane using graphene oxide and bacterial nanocellulose. It's highly efficient, long-lasting and environmentally friendly -- and could provide clean water for those in need.

Researchers have developed a way to dramatically enhance the sensitivity of nuclear magnetic resonance spectroscopy (NMR), a technique used to study the structure and composition of many kinds of molecules, including proteins linked to Alzheimer's and other diseases.

Scientists have developed tiny elastic robots that can change shape depending on their surroundings. Modeled after bacteria and fully biocompatible, these robots optimize their movements so as to get to hard-to-reach areas of the human body. They stand to revolutionize targeted drug delivery.
